A trade group for drone aircraft manufacturers and operators has released the industry’s first code of conduct in response to growing privacy concerns.

The Association for Unmanned Vehicle Systems International said Monday that the recommendations for “safe, non-intrusive operation” are meant to guide operators and reassure a public leery of the possibility of spy drones flying undetected over their homes.

“We understand as an industry that we’ve got a public relations problem,” said Paul McDuffee, a director of the association who helped draft the recommendations.
